Two types of bending waves are known to exists the.traveling waves and the inhomogeneous waves. During passage through one of the two above-mentioned connections between the three rods, both types of waves are partly refleuted, and partly they pass through. For calculating the reflection and transition coefficients of the intermedi- ate rod, it is necessary that the system consisting of eight linear equa- tions be solved.

Equation (6) may further be used for determining the conditions at which bending waves are not reflected from the intermediate rod. It is shown that with a certain material of the intermediate rod, by suitable selection of its thickness, ai, total reflection-tree passage of the bending waves may be attained. In them same wayl the oondition for the lack of a reflection of the inhomogeneous waves on the intermediate rod is formulated. There are 6 referenotes I Soviet-bloc.

In this method the propagation of the flexuralwave is treated as the interaction of a homogeneous rod and a load by means of forces and moments of the reaction forces. This makes it possible to express the haxT)onic motion of the homogeneous rod under the influence of these forces and mo- ments, as wen as the motion of the load, in terms of a certain second-order matrix~ so that the rod and the load can be treated like two-port networks, and the dispersior equation is the equation for the natural frequencies of the coupling of these two- port networks. 1~ases of zero load and of inertial and elastic loads are considere!9..

The process is shown to depend on maintaining an even permeability of the bed of the high-heat- release fire chamber relative to the air --- which can be done by scattering the fuel over the bed with the aid of a rotary stoker. This chamber, of the high -thermal- st res s type, burns anthracite efficiently and is equal to the demands made on modern power units. 1. Combustion chambers-'~es!,Tri 2. '"Dal R.P.

Tests should be of short duration but should not damage the product. Electrical qualities may be assessed by measurements of the Insulation resistance or the capacitance of the insulation before and after testing. Both types of measurement were made in the present work. The ratio of the capacitance at a frequency of 2 c/s to that at a frequency of 50 cls was also measured. The recommended procedure is to measure the capacitance of the insulation during the process of humidification and to determine the relative increase in permittivity of the Card 1/6 insulation. Graphs are then constructed of the increase in permittivity as a function of humidifiaation time and SOV/110-59-9-19/22 The, Principles of Humidity Test Cr-;nd--Jt-Jcns on Products Intended for Tropical Ser-dice the graphs for ma-~,hinez of xxoz-ma-l and ti-~pical design are .,ompart~d.

Electrical equipment in the chamber was exposad to a :..*elative Lumidity of 98-100% at temperatures of 2'0, 401 55 and 70 OC for 10-30 days. SOV/3.10-59-9..19/22 The Principles .-f Humidity Test Conditions on Products Intended for Tropical Service Moreover, at 40 and 55 OC the equipment was exposed to humidity cycles for 10-20 days. Each cycle lasted 24 hours and consisted of 6 or 18 hours at 98-100% humidity at the test temperature with subsequent cooling for 18 or 6 hours. These cycles were called 6 - 18 and 18 - 6 respectively. Similar equipment was also exposed under na'---iral conditions at Shanghai in the wet season. The climatic conditions are described. Graphs of changes in permittivity against time during tests in the tropical testing chamber at various temperatures are given in Figs 1 to 3 It will be -een that humidity testing for 13 days at 40 OC does not differentiate between tropical and normal insulation. However, at 55 Oc there is an appreciable difference from the fifth day onwards. The difference is revealed even more quickly at 70 OC but at that temperature even the tropical -4nsulation deteriorates so quickly that the difference diminishes again. It Card appears, therefore, best to make the test at 55 OC for 3/6 seven days.

Figs 4 and 5 show graphs of the Increase In permittivity as function of time on continuous exposuze to humidity at various temperatures, The curves in Fig 6 show the degree of ao.,celeratilon of the tests made at high temperature as compared with those made at 20 OC. At 70 OC az3celeration is by , factor of about 30, at 55 OC by a factor of 10, and at 1+0 OC by a factor of 2.5-3. It is a_-c.-ordingl rer;ommended that the best test duration at 40 0%'j is 21-2K days, assuming that t4oe best test time at 55 OC is 7 days. Continuous and cycled humidity tests are then compared. It will be seen from the curves given in Figs 7 and 8 that the conditions of 18 hours humidity followed by 6 hours cooling are the most severe. The re---ommendation that the humidity tests should be cyclic and not ooritimious is confirmed by the attitude of the Indian Delegation to the Stoqkholm Session of the I.E.C. In 1958 and by othe.- published work. In Card V6 addition to test-chamber results the curves of Figs 4 and 5 show also rihanges in permittivity during exposure under natural conditions in Shanghai. It is concluded that, SOV/110-59-9-19/22 The Princibles of Humidity Test Gonditions on Products Intended for Tropical Service approximately, a tropical chamber test of 21 days at L~OOC with the 16 - 8 cycle is 20-25 times more severe than natural exposure. Thus the chamber test of 21 days is approximately equivalent to 1-lj years' natural tropical exposure, The factors that influence the rate of humidification of insulation are briefly discussed. The tests may be made at constant relative humidity but different temperatures. In this connection curve 1 of Fig 6 indicates that as the temperature is raised the rate of humidification increases more rapidly than does the total humidity present. Tests may also be made at different total humidity at various temperatures, and in this case the lower the temperature the higher the relative humidity. k1so, humidification is then more rapid at the lower temperature. This was confirmed by tests on Card 5/6 stators of normal and tropical construction; test results aro plotted on Figs 9 and 10, to show change of SOV/110-59-9-19/22 Th-, Principles of Hwmidity Test Condition.,; on Products Intended, 4~ 1.n,:, Tropinal.

(USSR) ABSTUCTs It is I'Micult to study the way that slag is separated and trapped iiLi cyclone furnaces under normal operating conditions. Accordingly, it is of interest to study cold models in which the liquid slag surface is represented by a film of viscous liquid and the drops of liquid slag by solid particles in suspension. Tests in the cold arev however, not entirely representative because of the effects of conbustion on the aerodynamics of the process. This work attempts a more careful study of the separation of suspended particles from a swirling flow on to a film of viscous liquid, applying the theory of similarity. The equipment used in the experiments was a horizontal section of tube, fitted with various measuring instruments and attached to the discharge Bide of a fan., Me various separator models shown in fig.l. were connected to the open end of the tube. The inside of the models was lined with cloth coated with vaseline. The dusty-particles, obtained by Card 1/5 winnowing, were fed into the inlet tube at a suitable distance from SOV/96-58-6-13/24 An investigation of the separation of solid suspended particles on to a liquid film with a swirling gas flow. the inlet to the model. The dust consisted of crystals of K2Cr207 with & 8POcific gravity of 2.69 x 103 kgjm3- There is not compItte agreement about the criteria that govern the separation of dut in cyclones. Some consider that Ahen the resistance of the particles follows Strokes' law, the governing criteria are those of Stokes and Frouds; others consider that the process of separation is governed only by the Stokes criter4on. A special study of this point was accordingly made. A nmmber of effects that occur in dry cyclones were absent, because once a particle of dust touched the sticky wall it was trapped. The tests were made on geometrically similar models installed vertically with tangential flow inlet as shovn in fig.l. The diameter of the mode2a ranged from 50 to 400 nz, and the length was four diameters. Separation was improved by increasing the si2e of particles and the rate of flow, and by decreasin& the diameter of the model. The results are plotted as functions of Stokeo'criterion in fig-2., and it is shown that this criterion is the governing one.

Change in Fronde's criterion over very wide limits has no influence on the process of separation. A plot of the change in the coefficient of dust distrAoution along the length of the ch3nber with tangential inlet is given in fig.3. Most of the dust is deposited in the first section of the chamber, and the character of the curves alters very little with changes in the Strkes' criterion. In an actual cyclone, combustion reduuos the swirling of the flow. To study the effect of changes in swirl mpon dust separation, tests were made in a cylindrical chamber 100 mm diameter and 400 am long, with various swirlers having blades sat at different angles. The resultant relationship between the dagree of separation and Stokes' criterion is plotted in fig.4. The change iu degree of separation along the length of the chambers with bladed swirlers is plotted in fig.5, which shows that if the swirl of the flow is increased more dust is deposited in the early stages. It follows that to get good separation in short chanbers, good swirling is required, and that if the chamber is long the reduction in swirl that results from combustion will be less damaging than if the chamber is short. To study the influence of the shape of the chamber, tests were mRde with cylindrical chambers having various ratios of chamber to swirlar Card 3/5 diameter, and on square and rectangular chan ers. The same swirler An investigation of the separation of solid suspended particles OOV/96-58-6-13/24 on to a liquid film with a swirling gas flow. was used in all tests. The results are plotted in figs. 4 and 5. The transition from round to square to rectangular shape reduce$ the separation of dust, the effect being most marked in long chambers. Reduction in the diameter of the swirler relative to that of the separator reduced the separation, particularly in long chambers. Analysis of the experimental data yields a generalized relationship that nay be used to determine the degree of separation of dust in varioualy-proportioned chambers Vith bladed swirlers with various amounts of swirl. Tests were made on a 1/5 - scale model geometrically similar to a cyclone pre-furnace of the All Union Thernotechnical Institute. The three burner arrangements depicted in fig.7. were used. The graphs in fig.8. show the relationship between the total degree of separation and the flow of air in the chamber. Dust in trapped beat when all the air is passed through the bladed burner, and worst when 80% of the air passed through the tangential nozzle and the rest through the bladed burner. Thum, it may be supposed that with an equipment of given resistance to flow, the best burner arrangement, when the fuel is Card 4/5 An investigation of the separation of solid suspended particles SOV/96-58-6-13/24 on to a liquid film with a swirling gas flow. of high volatiles content, in one in which all the fuel dust and air are passed through the bladed burner.

Tests were accordin62y made to study the influence of tube bundle geometry, rate of gas flow, particle size distribution and other factors on the process of ash-arrestinb. The tests were made in a vertical duct of 100 x 100 mm containin6 model tube bundles and connected to an extraction fan. The tubes were smeared with petrolatum to represent molten slag. The dust used was potassium bichromate, and rte quantity trapped was determined by iodometric methods of analysis. The various models of bundles of tubes that were tested are shown in Fig 1. In the main test the tubes were 5 mm diameter, which is about 1/20th of the diameter used in practice. The efficiency of Card 1/6 arresting was evaluated by Eq ~2) which is in terms of ~X SOV/96-59-12-10/20 The Arresting of Suspended Particles Flowin6 Isothermally Throu-h a Bundle of Tubes Coated with Viscous Fluid the ratio of the quantity of material trapped to the average content of the material in the flow at inlet to the bundle. The tests made with different construc- tions of tube bundles were carried out with dust of 12 to 18 microns at a rate of flow of 16 m/sec. The distribution of the effectiveness of dust-arresting by tubes in different rows is plotted in Fig 2. The second row of tubes was always the most effective because of the local increase in the particle content of the flow immediately ahead of them. The increase was due to the passage of the flow over the first row. In general, the second, third and presumably successive rows are approximately as effective as the first one. In order to determine the influence of the main physical factors on the process of dust separation, tests were made with the first model. It had three bundles, each comprising four rows of tubes; the rates of flow ranged from 2 to 30 metres per second, with particle sizes ranging from 0 - 12 to 75 - 90 wicrons, and tube diameters of Card 2/6 5 and 10 mm. Test results obtained at various rates SOV/96-59-12-lo/20 The Arresting of Suspended Particles Flowing Isothermally Throu&~_ a Bundle of Tubes Coated with Viscous Fluid of flow are plotted in Fig 3. It will be seen that within the range of 8 to 30 m/sec there is very little increase in the efficiency of separation of dust by the first two rows, but a somewhat greater improvement in the third and fourth rows. The influence of dust particle size on the effectiveness of separation at various rates of flow is plotted in Pig 4. The curves show that larger particles promote separation, particu- larly by tubes in the first two rows. The relative effectiveness of successive rows with different particle sizes is discussed, Doubling the diameter of the tube was found to slightly decrease the amount trapped by the tubes of the first and second rows. The resistance of the bundles of tubes related to the rate of flow in the narrow section between tubes for various values of Reynolds number, number of rows and pitch of tube, are plotted in Fig 5. The relationship between the resistance and Reynolds number is not clearly expressed. The Card 3/6 factors governing the resistance are discussed. it is SOV/96-59-12-10/20 The Arresting of Suspended Particles Flowing Isothermally Tlirou~,h a Bundle of Tubes Coated with Viscous Fluid usually considered that the Stokes' number alone determines the process of separation when a dusty flow passs over a cylinder. It is here shown that the Froude number also has an effect, partici.larly-for the first two rows. Fig 6 indicates that all the experimental points can be plotted on a single curve if the efficiency of arresting is plotted as function of a complex that includes the Stokes, Froude and Reynolds numbers in the correct proportions. It will be seen from Fig 7 that the process of separation on the third and fourth rows can be des- cribed with sufficient accuracy by the Stokes' number. Fig 8 shows curves of the efficiency of arresting for various rates of flow. This graph may be used to make calculations on slag-arresting by tube bundles with a square arrangement; there can be any number of rows of tubes, their spacing across the flow being 2 - 4 diameters, and in line with the flow 2 - 3 diameters. The efficiency of arresting is given by expression (5), for particles of a particular size; when the flow Card 4/6 conzains a wide range of particle sizes, exDression (7) V~ SOV/96-59-12-10/2C The Arresting of Suspended Particles Flowing Isothermally Throu~;h a Bundle of Tubes Coated with Viscous Fluid should be used. Ash-removal factors for various two- and four-row arrangements of tube bundles are plotted in Fig 9 as functions of gas speed and tube arranGement. This graph also can be used for practical calculations. The ash-removal by various tube arrangements was calcu- lated for a flow of air containing dust of the particle size distribution found at the inlet to the induced- draught fan of a power station burning Zakamsk coal. In this case there is no evident advantace to be gained by C) leaving a clear space between successive bundles of tubes. It is concluded that twin tubes should no6 be used in this type of ash arrester. In general, tnese ash a-rresters can be very effective in a cyclone furnace, and cause only a small increase in the head of draught. In particular, if four bundles, each comprising two rows, are fitted beyond the cyclone chamber the ash-removal factor can be increased from 80 to 88.5%, or from 85 to Card 5/6 91.4% with a draught increase of approximately 45 mm of V SOV/96-59-12-10/20 The Arresting of Suspended Particles Flowing Isothermally Throu~;h a Bundle of Tubes Coated with Viscous Fluid water.

The quantity of dust deposited on this surface may be determined according to various physico-chemical methods (Ref 1). As the minimum size of the dust particles absorbed by a device is determined by the dimension of the latter, experiments must be carried out with the finest particles in order to attain greater efficiency of the device. Several experiments (Ref 2) showed that greater quantities of fine dust may be absorbed on a viscous surface than was stated in a paper by N. F. Dergachev (Ref 1). In order to solve thie problem experiments were carried out with a model with a tube having Card 1/2 a diameter of 50 mm and a length of 200 mm with various 05757 On the Initial quantity of Dust in Working With SOV/32-25-10-46/63 Models of Dust Collectors ASSOCIATION: quantities of a fine (0-12 p) dust of X2Cr2 07 at a tangen- tial air flow velocity of 7 m persecond, It was found that a variation of the quantities of dust from 9.6 to 205 mg (Fig; diagram) influences neither the total degree of separa- tion nor the distribution of the deposited particles along the model. Thus, when working with fine dust (0-12 p), the initial quantity may be much higher than previously stated. There are 1 figure and 3 Soviet references.
